Muntean Cristina Ioana

My main research interests are in Information Retrieval and Machine Learning. I am particularly interested in neural and classic IR models, NLP and LLMs, applied to Conversational Search.

I will be attending the following events:

• 6-10 April 2025: Reproducibility Chair ECIR'25 in Lucca, Italy

Past events:

• 21 October 2022: MICROS Workshop Chair @ CIKM 2022, Second Edition.
• 1 April 2021: MICROS Workshop Chair @ ECIR 2021, First Edition.

My papers are at the crossroad of IR, ML and NLP, with particular focus on Coonversational Search.
